CPT® Code 64836

The procedure described by CPT® Code 64836 involves the surgical suture of a single ulnar motor nerve. This nerve is a critical component of the peripheral nervous system, primarily responsible for motor function in the hand. The suture repair of the nerve, often referred to as end-to-end closure, is a technique employed to restore continuity and function following nerve injury. The procedure can be performed using various techniques depending on the location and extent of the nerve damage. For injuries that are more distal, an epineural closure technique is typically utilized, where the outer layer of the nerve, known as the epineurium, is sutured to bring the two ends of the transected nerve together without applying tension. In contrast, for more proximal injuries, a perineural closure technique may be employed, which involves suturing the individual fascicles of axons within the nerve. This method allows for a more precise alignment of the nerve fibers that are responsible for specific functions, ensuring optimal recovery and restoration of motor capabilities. The procedure is critical for patients who have sustained nerve injuries, as it aims to restore normal function and alleviate symptoms associated with nerve damage.
